Fabricated concrete variable section T-shaped shear wall component and construction method thereof

Abstract

The invention belongs to the technical field of building materials and building construction, and particularly relates to a fabricated concrete variable section T-shaped shear wall component and a manufacturing mold and a construction method thereof. The T-shaped shear wall component comprises an X-direction wall column (11) and a Y-direction wall column (12), and the X-direction wall column (11)and the Y-direction wall column (12) are mutually wing walls. The T-shaped shear wall component is divided into a component upper section (1A) and a component lower section (1B) which is formed by tapering the variable section, and a whole body formed by concrete pouring. Through the variable section, vertical rebars (101) on the two sides of the component lower section (1B) and a rebar joint (1C)of an edge component vertical rebar (1051) are exposed, and thus the problem that connection between a vertical rebar (101) of the T-shaped shear wall component and the edge component vertical rebar(1051) is insecure can be conveniently solved by adopting a welding connection method. By arranging a special vertical drill way (104) for cast-in-place concrete (32), the cast-in-place concrete (32)can be easy to pour and vibrate to be compact, and accordingly quality defects are avoided.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and relates to a shear wall component used for building structures, in particular to an assembled concrete variable-section T-shaped shear wall component, a manufacturing mold and a construction method thereof. Background technique [0002] Assembly building is to connect the same kind of prefabricated components or different kinds of prefabricated components. Since the reinforced concrete shear wall is integrated with concrete and steel bars, it is necessary to solve the connection problem of the longitudinal and vertical reinforcement of the shear wall, especially the shear wall. The connection problem of vertical reinforcement at the bottom. At present, the connection of vertical reinforcement at the bottom of prefabricated reinforced concrete variable cross-section T-shaped shear wall members mostly adopts the sleeve grouting method, and there are many prob...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, it is difficult to stagger the horizontal reinforcement joints of a large number of cast-in-situ cast-in-place concrete variable-section T-shaped shear wall components at present, and the vertical reinforcement connection adopts sleeve connections that are not firm and inconvenient to operate. The quality is difficult to guarantee. T The reinforcement of the type shear wall member does not form the steel bar skeleton and other problems. The first purpose of the present invention is to provide a kind of prefabricated concrete variable section T-shaped shear wall component. By improving the prefabricated concrete variable section T-shaped shear wall component Structural design, by changing the cross-section of prefabricated reinforced concrete variable cross-section T-shaped shear wall members, the vertical steel bars protruding from the lower part of the upper part of the exposed members on both sides of the lower part of the exposed members, and the steel bar joints of the vertical rebars of the edge members, using the traditional and simpler method The steel bar welding connection method solves the connection problem of the vertical steel bar of the T-shaped shear wall member and the vertical steel of the edge member; the connection of the horizontal steel bar and the failure of various steel bars are solved by the method of the integral prefabricated concrete variable-section T-shaped shear wall member. Interconnection to form a steel skeleton; the method of reserving special vertical channels for cast-in-place concrete is adopted to ensure that the concrete is poured and vibrated compactly during on-site installation; the second purpose of the present invention is to provide a prefabricated concrete variable section T The making mold of type shear wall member; The 3rd purpose of the present invention is to provide a kind of construction method of assembled concrete variable section T-shaped shear wall member, solve the mold making of assembled reinforced concrete variable section T-shaped shear wall member The use of T-shaped shear wall components and the production and installation methods
